Optical photographic printing apparatus



March 11, 1969 R. c. KAU FFMAN OPTICAL PHO' I'OGRAPHIC PRINTING APPARATUS Filed; March 11, 1966 FIG] ' IN VENTOR @ml (2. [W040 United States Patent 2 Claims ABSTRACT OF THE DISCLOSURE A print holding device for photographic printing having a rectangular fiat print receiving member that is adjustable to any angle. Two parallel spaced, permanent magnets are carried on the upper surface of the member together with two freely movable permanent bar magnets so that holders for different sized prints are provided.

My present invention relates to improvements in optical photographic printing apparatus, one object of the invention being the provision of a print support that is so adjustable as to assist in relieving distortion and thus improve the final photograph.

Another object of the invention is the provision of a means operated by hand to lift one edge of the print so that it is more easily removed from its printing position.

Still another object of the invention is the provision of magnetically held guides that insure rapid adjustment of the print upon the platform of the rectangular support.

To fully understand this invention, attention is invited to the accompanying drawings, in which:

FIGURE 1 is a top plan view thereof;

FIGURE 2 is a side view thereof, slanted in one of the several positions the platform may assume; and

FIGURE 3 is a section on line 3-3 of FIGURE 1.

Referring to the drawings, the numeral 1 designates a rectangular flat support or platform, to be constructed of any suitable material, such as wood, metal or plastic, having embedded therein on its top surface permanently magnetized metal strips 2, 3, 4 and 5, arranged in pairs, so that the print-holding or engaging guides 7 and 8 can be readily slid to the desired position to engage opposite edges of the emulsioned sheet 10, which is here shown as paper, but may be Celluloid or glass.

Openings 11, three in this instance, are provided in the platform and mounted in each opening is a compression member 12 with a lock nut 13 to clamp the adjustable leg 14, here shown as a slideable cylindrical mem- 3,432,233 Patented Mar. 11, 1969 her, so that the platform may be set at the desired tilt or angle to best have the print exposed. Other places as shown in dotted lines 14 may be openings for other'legs, as may be required.

When the print, here shown as paper-backed, means for lifting one end thereof adjacent one of the guide strips, and this consists of a wire 15 having a right-angled terminal 16, fitted to enter the small opening 17 in the platform so that by means of pressing the handle downwardly, the edge of the print is lifted for easy removal from the platform.

From the foregoing description taken in connection with the drawings, it is evident that here is provided a print holding means for optical printing of photographs that will present the positive print at the desired angle to suit the intention of the printer, and to correct distortions that may be present in the negative.

What I claim as new is:

1. A print-holding device for optical photograph printing apparatus, including a rectangular, flat, adjustable print-holder, a plurality of adjustable legs to regulate the angular position to which the platform is to be set, an adjustable print-holding means consists of two parallel and opposed permanently magnetized bars mounted in the platform, and two freely slidable print limiting guides of magnetic material to be slidable adjustable relative to the permanent magnetized bars.

2. A print-holding device for optical photograph printing apparatus, including a rectangular, fiat, adjustable print-holder, a plurality of adjustable legs to regulate the angular position to which the platform is to be set, an adjustable print-holding means consists of two parallel and opposed permanently magnetized bars mounted in the platform, two freely slidable print limiting guides of magnetic material to be slidable adjustable relative to the permanent magnetized bars, and manually operated means carried by the platform to lift one edge of a print.
